3rd link: a new more modest and cheaper version

The new “twin-tube” version of the Quebec-Lévis tunnel will cost less than $7 billion and to ensure better fluidity, lanes will be reserved for buses only during peak hours, our Parliamentary Office learned.

After placing the cost of a first version of the project between $7 and $10 billion last year, the Legault government will now indicate much more precisely what it will cost to materialize its promise of the third link, downtown to downtown.

According to reliable sources, this fixed cost will also take into account the risks associated with the realization of such a megaproject.

The choice of a two-tube tunnel, instead of the world’s largest single-tube two-storey presented in May 2021, should facilitate its realization while reducing costs, since more companies with expertise in the field will be able to try to embark on the adventure, we are assured.

Rush hour

Unlike the previous version, some lanes will be reserved for buses, but not at all times. There will therefore not be a lane reserved exclusively for public transport.

The Ministry of Transport will instead rely on dynamic lane management, so that at least one lane is reserved for buses during peak hours, during which heavy trucks will not have access to the tunnel.

Our Parliamentary Office also got its hands on an argument that the Minister of Transport, François Bonnardel, and the Minister responsible for the Capitale-Nationale, Geneviève Guilbault, can refer to during the presentation of the new version of the project scheduled for 1 p.m. , in Lévis.

Capacity exceeded

To justify the relevance of its megaproject, the Legault government will argue, among other things, that by 2036, 36,800 additional inter-river trips will worsen traffic, which has increased by more than 20% in nearly 20 years on the two current aging bridges.

Barely a few years after the inauguration of the tunnel, Quebec estimates that 143,000 vehicles per day will cross the Pierre-Laporte bridge, whereas it was designed for a daily flow of 90,000 vehicles and 126,000 are recorded per day.

By way of comparison, the average daily traffic on the Louis-Hippolyte-La Fontaine bridge-tunnel is 121,000 vehicles in the greater Montreal area, which can count on 34 bridges for a population of 4 million inhabitants.

Without Francois Legault

Premier François Legault, who participated in the unveiling of the Réseau express de la Capitale (REC) last May, will not participate in what his government considers an “update”.

The mayors of Quebec and Lévis, who were treated to a private presentation on Tuesday, will attend the government announcement.

Some examples of the reasons in favor of 3and privilege

  • The current flow of the Pierre-Laporte bridge is 126,000 vehicles per day, while it was designed to 90,000and that 143,000 vehicles should circulate there in 2036.
  • By way of comparison, the average daily flow on the Louis-Hippolyte-La Fontaine bridge-tunnel is 121 000 vehicles ; Mercier Bridge: 71 000 ; Victoria Bridge: 23,600.
  • The greater Montreal region relies on 34 bridges for a population of 4 million inhabitants, compared to two intershore links between Québec and Lévis.
  • The city center to city center route for buses will be 8.3km compared to 26 kilometers with current bridges.
